On Monday, September 3, SpongeBob’s adventures continue when Nickelodeon treats viewers to an all-day SpongeBob SquarePants marathon from 9:00 a.m. – 8:00 p.m. with two brand-new episodes, “Squid Baby” and “The Good Krabby Name,” premiering at 7:30 p.m. (ET/PT). During “Squid Baby,” Squidward hits his head and reverts to being a baby, and it’s up to SpongeBob and Patrick to take care of him. Next in “The Good Krabby Name,” Mr. Krabs wants all of Bikini Bottom to eat at the Krusty Krab, so SpongeBob and Patrick go on an advertising blitz.

SpongeBob fans can continue to get their nautical fill throughout the week from 5:00 p.m. – 6:00 p.m. (ET/PT) with back-to-school episodes airing daily. This week of under the sea fun all leads up to the premiere of “License to Milkshake” featuring guest voice Michael McKean (This is Spinal Tap; Planes, Trains & Automobiles) on Friday, Sept. 7, at 8:00 p.m. (ET/PT). During the episode, SpongeBob learns his milkshake license has expired and is forced to go back to the milkshake academy. McKean voices the academy instructor.
